NEWSER -- Turns out there is a cool use for trigonometry: Scientists in Colombia have been able to calculate the trajectory of the meteor that injured 1,000 in Russia this month using data gleaned from local camera footage and a lake landing spot.

Experts in Russia, meanwhile, have learned more about the object itself.

It's called a chondrite-the most common kind of space rock near Earth. And, as Popular Sciencereports, it spent 4.5 billion years in space before rocking Russia.

Volunteer skiers traversed 31 miles of its debris field this weekend, picking up more than 100 pieces, the largest of which weighs in at about 2.2 pounds. Some chunks are being sold online for as much as $16,000, though they haven't been authenticated, Russia Today notes; guides have started offering tours of the impact area.
